Prescription serengeti - Serengeti Medium Aviator Progressive Sunglasses

Serengeti's are outstanding, as usual. Getting prescription lens over the internet is a little unsettling. If you don't have perfect measurements, then you may have a problem. My lens came with progressive bifocals which I requested to be set low so it doesn't interfere with my long vision but they came back VERY low requiring me to position my eyes like I want to see something on my cheek just so I can read a piece of paper or a book. This normally would be unacceptable with a normal pair of prescription lens, but since this is only a pair of sunglasses that will primarily be used for long vision, and because it would be too much trouble fighting with the distributor, returning the product and wait another month for another new pair of glasses to arrive, I will accept them as is.
